SECTION IV. HEALTH HAZARDS

PRIMARY ROUTE(S) OF ENTRY

Skin and eye contact and inhalation are the most likely exposures.
Ingestion is possible.

TARGET ORGANS                    Skin, eyes, lungs, respiratory system

HEALTH EFFECTS

Eyes                             Contact with solution can be intensely
                                 irritating. Noticeable irritation to eyes
                                 from ammonia vapor occurs at
                                 concentrations of 100 ppm.

Skin                             Solution can irritate skin. Exposure to
                                 strong solutions may result in severe
                                 burns and pain. Ammonia gas can be
                                 irritating to moist skin.

Inhalation                       Ammonia gas may cause varying degrees of
                                 irritation to mucous membranes and
                                 respiratory passages.

Ingestion                        Ingestion of solution may result in oral,
                                 esophageal, and stomach burns.


EXPOSURE LIMITS                  No exposure limits have been set for aqua
                                 ammonia.

Products of decomposition or combustion are toxic ammonia and nitrogen
oxides.

Ammonia:           Threshold Limit Value (TLV) = 25 ppm
CAS # 7664-41-7    (American Conference of Governmental Industrial Hygienists)
                   LCLo = 2000 ppm/4 hours (rats)

Nitrogen Dioxide: Threshold Limit Value (TLV) = 3 ppm (ACGIH)
CAS # 10102-44-0 LC50 = 67 ppm/4 hour (rats)

MATERIAL SAFETY DATA SHEET                          PRODUCT:   Aqua Ammonia

SYMPTOMS OF OVEREXPOSURE

Acute                              Headache, salivation, burning of throat,
                                   perspiration, nausea, vomiting, or coughing

Chronic                            None found

Notes to Physician                 Exposure to high concentrations of ammonia
                                   gas may result in pulmonary edema, often
                                   appearing 6 hours or more after exposure.
                                   Bronchopneumonia may develop.

POTENTIAL HEALTH HAZARD DATA (IARC, NTP, OSHA)

Ammonia gas is listed in OSHA Subpart Z as a sensory irritant.

SECTION V. FIRST AID PROCEDURES

Eyes         IMMEDIATELY flush thoroughly for 15 minutes with large amounts
             of clean water, occasionally lifting upper and lower lids.
             Seek medical attention.

Skin         IMMEDIATELY wash thoroughly with large amounts of clean
             water. Remove contaminated clothing, wash or clean before
             wearing again.

Inhalation   Remove to fresh air. Administer artificial respiration if
             patient is not breathing. Administer oxygen if patient has
             difficulty breathing. Seek medical help.

Ingestion    Seek medical help immediately. If immediate help is not
             available, have conscious person drink large amounts of
             water. DO NOT MAKE PERSON VOMIT. Egg white, olive oil, or
             milk may be given to a conscious person. Keep the person
             warm. Watch for shock. Do not force an unconscious person
             to drink or vomit.

SECTION VI. SAFE HANDLING AND USE

Hygienic Practices   It is advisable to wash promptly if skin becomes
contaminated, before eating or smoking, before using toilet facilities, and
at the end of the work shift before leaving worksite.

Storage   Store in cool, well-ventilated areas. Containers with plastic or
rubber plug must not be filled to the brim.

Maintenance   Zinc, silver, copper, and copper-base alloys such as brass are
rapidly corroded by moist ammonia vapors.

---------------------------------------------------------------------------

SECTION VII. PERSONAL PROTECTION

Ventilation         Adequate ventilation to keep ammonia concentration below
                    the OSHA standard of 35 ppm.

Eyes                Appropriate goggles should be used for transfer operations
                    or where splashing may occur.

Skin                Wear rubber gloves for transfer operations or where
                    splashing may occur. If irritation occurs, impervious
                    clothing and gloves should be worn.

Respiratory         Where ammonia vapors exist in concentrations above the
                    standard, respiratory protection should be provided. A
                    full face mask with ammonia cartridge can be used in
                    vapors up to 500 ppm. Above this limit and in unknown
                    concentrations, use a full face self-contained breathing
                    apparatus.

SECTION IX. ENVIRONMENTAL PROTECTION

Procedures for Cleanup of Spills and Leaks

     Aqua ammonia is a plant food. However, large spills could possibly
     kill vegetation or cause illness in animals. Contamination of
     waterways could possibly cause fishkills. Prevent large quantities
     from contacting vegetation or waterways. Keep animals away from large
     spills. Dike spill area if possible to prevent spread.

Reportable Quantity (CWA/CERCLA) 1000 pounds
         (SARA Title III)        None established

Waste Disposal Method

     If uncontaminated, recover and reuse as product. If contaminated with
     other materials, the nature and extent of contamination may require
     use of specialized disposal methods. Consult local, state, or federal
     regulatory agencies for acceptable disposal procedures and disposal
     locations.
